SELF-HEATING soLDERlNe-IRON.-

SPECIFICATION forming part of Letters Patent N o. 574,596,

dated January 5, 189'?.

Application filed February 1'7, 1896. Serial No. 579,525. (N o model.)

fo all whom t may concern:

Be it known that I, JOHN VICKSTROM, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in vSelf -Heating Soldering- Irons, of which the followingisa specification. This invention relates to improvements in y soldering-irons; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specically claimed.

The objects of my invention are, first, to provide a self-heating soldering-iron which shall be simple and inexpensive in construction, strong and durable, and effective in operation; second, such a soldering-ironthe parts of which shall be so constructed and arranged as to provide a handy and convenient implement or tool to be used by plumbers, tinners, cornice-makers, and other metal- Workers, in which the iron or copper head may be heated and kept hot While the tool is being used; third, a soldering-iron which shall have combined therewith and forming the handle thereof an air-pum p and gasolene-receptacle, and, fourth, to provide a means for regulating the temperature to which the iron or copper head may be heated.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in whichg Figure l is a view in elevation of a solderin g-iron showing it in its completed form and embodying my invention. Fig. 2 is a central longitudinal sectional View thereof. Fig. 3 is an enlarged cross-sectional View taken on line 3 3 of Fig. 2; and Fig. L is a central sectional view of a portion of the handle, gasoleue-receptacle, and air-pum p located in the handle,

showing the piston-rod thereof extended.

Similar letters refer to like parts throughout the different views of the drawings.

Arepresents a gasolene-receptacle, which may be made of any suitable size, form, and material, but preferably-cylindrical and of hard metal. Each end of this cylinder or receptacle is usually screw-threaded to engage the caps A and A2, which are internally screwthreaded, as shown, but which maybe sometimes otherwise secured on the cylinder. Near the outer end of the cylinder A, or that end thereof adjacent to the handle B, and on its inner surface is formed or provided au annular iiange o, against which rests a ring l), of soft metal or other suitable material, on the inner surface of the cap A2, to form a tight joint. The central portion of the inner surface of the cap A2 is provided with a tubular projection a', having an opening a2 at its inner part for the escape of the compressed air from the air-pump. Within this projection is placed a spring a3 to hold the check-valve a* for the opening a5 in said cap. Around the opening a5 and to the outer surface of the cap A2 is secured a tube or cylinder O, havingits outer end screW-threadedto engage the screw-threaded head D on the piston-rod D', the inner end of which is provided with a piston d, of leather or other flexible material, which fits snugly within the cylinder C. The piston d is secured on the rod D', between the soft-metal piece d on the inner end of the rod and a ring or Washer d2 near its inner end. The piece d is adapted to fitover ing a5 in the cap A2 when the piston-rod is in the position shown in Fig. 2 of the drawings, to prevent the escape of air from the cylinder A or gasolene-receptacle. t

' As shown in Figs. 2 and 4 of the drawings, the ring cl2 is somewhat smaller than the tube C, but serves to prevent the piston CZ slipping on the rod. Around the tube Gis located a handpiece I3, of wood or other suitable nonheat-conducting material. The cap A is provided near its periphery with an opening c into which is Iitted a tube E, to the outer end of which is secured a burner-head F. To the the open-V inner portion of the tube E and located Within the cylinder A is a tube E', which is formed with a number of perforations e in its surface adjacent to the wall of the cylinder, and has at itsfree end a sieve or strainer e' to prevent the passage ofany accumulations in the gasolene. To the outer portion of the burnerhead F is secured a hollow burner G, which is formed With perforations g, and in the free end of which may be secured, by means of setcrews 7L or otherwise, the copper head H, which is employed for melting and applying the solder. The burner-head F is provided IOO with a cent-ral longitudinal opening f, which l is formed tapering toward its outer end, and said opening communicates With the tube E through a channel f', through which the gasolene is forced. The rearportion of the burnerhead F is formed or provided with a screwthreaded projection f2, through which passes a screw-threaded rod i, which tapers at its inner end to correspond with the shape of the openingfin the burner-head. The outer end of the rod t' is provided with a transverse projection t" for adjusting the same, so that it may be forced forward into the opening f of the burn er or retracted to regulate the flow of the gasolene through the opening f into the burner G or holder for the copper head or soldering-iron, which is formed with its inner portion tapering, as shown, so that the flame will envelop the same and be divided thereby, thus causing the iron or head to be more readily heated, and especially so when the implement is used in the open air, than if the flame was forced into a hollow iron or head.

From the foregoing and by reference to the drawings it will be seen that by removing the cap A2 from the cylinder A the gasolene or other oil to be used may be placed in said cylinder and safely confined therein by means of said cap, the spring-held valve d serving to prevent its escape through the opening ai". Vhen it is desired to force the gasolene through the tubes E and E into the opening f, the head on the piston-rod may be disconnected from the tube C, when by operating said rod back and forth air will be forcedA into the cylinder A and compressed therein, thus causing the gasolene to be forced into the tube E through its perforations e and absorbent material e2, and out into the tube C, from whence it will flow into the chamber or openingfof the burner-head, where as soon as it (the burner-head) becomes heated gas will be formed, and by the pressure Within the receptacle be forced through the opening f into the burner or holder G against the copper head or soldering-piece, which may be heated to any desired degree by the ame produced by the escaping gas. By turning the rod i by means of the extension il it is apparent that the said rod will be extended or retracted, thus regulating the iiow of the gas through the opening f of the burner-head.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination oi the cylinder A, provided with the internal annular flange a, the cap A2, having the ring b, tubular projection a',and openin g a5, the spring-held check-valve d4, located in the projection a', an airpu1np secured to the outer surface of the cap A2, and communicating with the oil-receptacle, and having on the end of the piston-rod adjacent to said cap a piece d', to close the opening therein, substantially as described.
